A voltage transformer is used to convert the electrical output of a power source to match the voltage of your device, that is, to convert 110 volt to 220/240 Volt OR convert 220/240 V to 110/120 Volt. A "Step Up transformer" is needed when you want to use a 220 volt foreign appliance in USA with 110v. A Step Down transformer is needed when you want to use a 110V appliance in a 220V Country. Please read our Transformer Purchase Guide before choosing a voltage converter transformer.
